In this course, you’ll build upon your basic Python skills, learning more advanced topics such as object-oriented programming patterns, development of graphical user interfaces, data management, threading, unit testing, and creating and installing packages and … Unit testing is a technique in which particular module is tested to check by developer himself whether there are any errors. A unit test is a scripted code level test designed in Python to verify a small "unit" of functionality. The more unit tests you create, the longer it takes to run those unit tests. Unit testing is key to developing quality code. 3. # Advanced Python Testing.
